Hi all. Is it possible to ship smoked meats unrefrigerated if they're sealed in a vaccum pack? I was just curious, since I see smoked salmon vaccum sealed and sitting on shelves at room temperature at my local grocery store all the time. I was thinking it'd be nice to smoke up something for my mother across the country, vac seal it, and send priority mail, but I don't want to risk spoilage. I guess the alternative would be to get some dry ice and a small cooler, but I'm trying to keep the cost on the low end.
